Governor J. B. Pritzker says he will sign the landmark legislation

The yearlong, nail-biting drama over the fate of Exelon’s Byron and Dresden nuclear plants came to an end on Monday afternoon when the Illinois Senate gave its nod to S.B. 2408, a wide-ranging clean energy package that seeks to phase out fossil-fuel power generation in the state and place it on a path to 100 percent carbon-free energy by 2050.

With essentially no time to spare, the Illinois Senate early this morning passed a clean energy omnibus package that includes $694 million in assistance to three of the state’s financially troubled nuclear plants: Braidwood, Byron, and Dresden. The vote was 39–16. (Both the Senate and House had returned to the capital on Tuesday for a one-day special session to consider legislative redistricting.)

As Illinois lawmakers continue to debate energy legislation that would allow the state’s Byron and Dresden nuclear plants to continue operation beyond this year, Exelon would like to remind everyone—including those legislators, no doubt—of what is at stake.

Exelon on June 16 filed with grid operator PJM Interconnection to deactivate the two Byron reactors in Illinois. The move came one day after the Illinois Senate adjourned without reaching an agreement on a comprehensive energy package that would have provided nearly $700 million to keep Byron’s reactors, as well as Exelon’s Dresden and Braidwood nuclear power plants, in operation. (In August of 2020, Exelon announced that it would close the economically challenged Byron and Dresden facilities in the fall of 2021 without some form of state aid to provide compensation for their clean power.) The state’s House of Representatives also adjourned earlier this week without taking up the bill.

Three Illinois nuclear power plants—Byron, Dresden, and Quad Cities—did not clear in last week’s long-delayed PJM Interconnection capacity auction, Exelon Generation reported in a filing with the Securities and Exchange Commission.
The news is likely to further pressure the Illinois General Assembly to pass a comprehensive energy package—one with subsidies for the state’s financially ailing nuclear plants—before Exelon moves forward with its plan, announced last August, to prematurely retire Byron and Dresden.

A group of Illinois lawmakers joined Joe Duffy, executive director of the labor coalition Climate Jobs Illinois (CJI), at a virtual news conference on March 29 to unveil a union-focused, clean energy legislative proposal that includes help for the state’s struggling nuclear power plants.
